Ground-transmitted waves generated by machine foundation, traffic, or blasting may result in ground vibrations, causing distress to adjacent structures and disruption to the operation of nearby sensitive machinery. Most of the vibratory energy affecting nearby structures is carried by surface waves that propagate in a zone close to the ground surface. Therefore, it is possible to reduce the ground vibration significantly by placing a suitable isolation system beneath the surface of the ground. This paper presents the results of an investigation of different vibration isolation systems including floating slab tracks, wave impending barriers and trenches, which have been used to reduce the effects of machine foundation and traffic induced vibrations on nearby structures.
